Method and apparatus for implementing search engine with cost per action revenue model

ABSTRACT

The inventive technology enables the search engine operator to charge the advertisers who place their links on the search engine only if the user uses the search results to visit the advertiser&#39;s web portal(s) and generates revenue for the advertiser. This concept is especially attractive to the advertisers because it eliminates the risk, which the advertisers face in conventional search engines, when they are changed by the search engine per user click irrespectively of whether the user&#39;s visit resulted in advertiser&#39;s revenue.

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

The present patent application is related to commonly owned co-pendingpublished U.S. patent applications No. 2006/0265501 entitled “SYSTEM ANDMETHOD FOR ENABLING WIRELESS INTERNET ACCESS IN PUBLIC AREAS” and No.2007/0136295 entitled “COMPUTERIZED SYSTEM AND METHOD FOR ADVANCEDADVERTISING,” filed on the same day, which are incorporated by referenceherein.

FIELD OF THE INVENTION

The present invention relates generally to networking technology andmore specifically to a computerized networking search engine.

DESCRIPTION OF THE RELATED ART

Search engines such as Google derive their revenue from displaying tothe users advertisings paid for by sponsors. Specifically, in responseto the user query, a search engine performs a search of pre-stored setof web pages and returns the results containing information retrievedfrom the web. To generate its revenue, the search engine also shows theuser sponsored advertisements, which are usually placed above theresults retrieved from the web. When the user uses links associated withthe displayed sponsored advertisements, the sponsors pay the listingfees to the search engine, based on the number of users' visits.

The most significant problem associated with the conventional searchengines is that the advertiser pays the search engine fees withoutregard to the actual revenue derived by the advertiser from the usersdirected to the advertised by the search engine. In other words, theadvertiser must pay the search engine even if the visitors did not orderany goods or services from the advertiser. Essentially, the advertiserhas to estimate whether the fees paid to the search engine are justifiedby the additional customer traffic that it brings.

What is needed is a methodology and a system which would enable theadvertiser to pay the search engine an amount of fees based on theamount of additional revenue that the traffic from the search enginegenerates for the advertiser. Moreover, the need exists for a searchengine that pays its users back a portion of revenues generated by useractions and enables consumers to share in revenues from cost per actionadvertisers on the search engine. Such system would enable Internetusers to participate in the growing online search market and to receiverevenues generated by their online activities.

Additionally, the various embodiments of the inventionas described may be implemented in the form of a software running on ageneral purpose computer, in the form of a specialized hardware, orcombination of software and hardware.

The inventive technology enables the search engine operator to chargethe advertisers who place their links on the search engine only if theuser uses the search results to visit the advertiser's web portal(s) andgenerates revenue for the advertiser. This concept is especiallyattractive to the advertisers because it eliminates the risk, which theadvertisers face in conventional search engines, when they are chargedby the search engine per user click irrespectively of whether the user'svisit resulted in advertiser's revenue.

In addition, an embodiment of the inventive system track's user'sbehavior and authorizes payments to the users based on the share of therevenue received from the content providers.

FIG. 1 illustrates an exemplary embodiment of the computerized internetsearch engine system in accordance with an embodiment of the inventiveconcept. In FIG. 1, a client 101 send a search query 106, 107 to theinventive search system 103 through its web interface 102. The searchengine performs the search of the internet content by accessing 110 thesearch engine 105, which may be one of the well-known search enginesavailable on the Internet, including, without limitation, Google, Yahoo,MSN, Alta Vista, etc. The search engine 105 stores and indexes multipleweb pages in its internal storage. After executing the query 107, thesearch engine 105 returns the query result 111 to the search system 103.The search system 103 receives the query results from the search engine105 and integrates them with paid advertising materials that are storedin the paid advertising database 104. To this end, the search system 103issues a query 109 to the paid advertising database 104 in order toidentify the paid advertisements which best match the user's query 106.The search query results together with integrated advertisementmaterials 112 are sent by the search system 103 to the client 101through the web interface 102. In another alternative embodiment of theinventive concept, the search system 103 itself integrates an internalsearch engine subsystem (not shown), which is used to execute userqueries.

An exemplary embodiment of the search result page containing searchquery results together with integrated advertisement materials,designated in FIG. 1 by numeral 112 is depicted in FIG. 2. The depictedsearch result page includes “free” search results 203 and 204, whichhave been retrieved from the web. These results are also refereed to as“free” search results because they are not sponsored or paid for by anadvertiser. The result 202 is an example of a sponsored result or link,which has been retrieved by the inventive search system from the paidadvertisements database and inserted into the results page. If a useruses this link to access the advertiser website and makes a purchase, inaccordance with the inventive concept, the advertiser authorizes apayment to the search engine operator. The exact mechanism for trackingthe purchase transaction and recording the payment is not essential tothe present invention. Specifically, the purchase may be detected by theadvertiser's e-commerce system, which would also determine that thecustomer was sent to the advertiser's website by the inventive searchengine. Pursuant to this information, the payment may be recorded in anadvertiser's database. The sponsor-paid advertisement is designated insearch result page by numeral 202. Optionally, this page may contain thesearch term input field 205/206. Finally, the search result page mayalso include advertiser sponsored links inserted by the search engine105. Such links are not handled by the inventive search system and aredesignated with numeral 201.

The amount of the payment received by the operator of the inventivesystem from advertiser may have any predetermined relationship to theamount of revenue realized by the advertiser from the specific uservisit. One example of such relationship may be a proportionaterelationship or a certain percentage.

In an embodiment of the inventive system, portion of the paymentreceived by the operator of the inventive search system from theadvertiser is rebated back to the user. For this purpose, the user maybe required to establish a user account to enable the inventive systemto track user activities and to store information on the credit due theuser. To implement this functionality, the inventive system mayadditionally include a database system for storing user and paymentinformation. As will be appreciated by those of skill in the art, suchrebate system provides additional incentives for users to user theinventive system for searching.

It will be appreciated by those of skill in the art, the inventivesystem is not limited to interoperating with only one advertiser or onlyone external search engine. In an embodiment of the inventive searchsystem, the user may specify which external search engine should be usedto retrieve the web search results.

FIG. 3 is a block diagram that illustrates an embodiment of acomputer/server system 300 upon which an embodiment of the inventivemethodology may be implemented. The system 300 includes acomputer/server platform 301, peripheral devices 302 and networkresources 303.

A persistent storage device 308, such as amagnetic disk, optical disk, or solid-state flash memory device isprovided and coupled to bus 301 for storing information andinstructions.

Computer platform 301 may be coupled via bus 304 to a display 309, suchas a cathode ray tube (CRT), plasma display, or a liquid crystal display(LCD), for displaying information to a system administrator or user ofthe computer platform 301. An input device 310, including alphanumericand other keys, is coupled to bus 301 for communicating information andcommand selections to processor 305. Another type of user input deviceis cursor control device 311, such as a mouse, a trackball, or cursordirection keys for communicating direction information and commandselections to processor 304 and for controlling cursor movement ondisplay 309. This input device typically has two degrees of freedom intwo axes, a first axis (e.g., x) and a second axis (e.g., y), thatallows the device to specify positions in a plane.

An external storage device 312 may be connected to the computer platform301 via bus 304 to provide an extra or removable storage capacity forthe computer platform 301. In an embodiment of the computer system 300,the external removable storage device 312 may be used to facilitateexchange of data with other computer systems.

The invention is related to the use of computer system 300 forimplementing the techniques described herein. In an embodiment, theinventive search system 103 may reside on a machine such as computerplatform 301. In an embodiment, the management device locator server 106may also be deployed on a machine such as computer platform 301.According to one embodiment of the invention, the techniques describedherein are performed by computer system 300 in response to processor 305executing one or more sequences of one or more instructions contained inthe volatile memory 306. Such instructions may be read into volatilememory 306 from another computer-readable medium, such as persistentstorage device 308. Execution of the sequences of instructions containedin the volatile memory 306 causes processor 305 to perform the processsteps described herein. In alternative embodiments, hard-wired circuitrymay be used in place of or in combination with software instructions toimplement the invention. Thus, embodiments of the invention are notlimited to any specific combination of hardware circuitry and software.

The term “computer-readable medium” as used herein refers to any mediumthat participates in providing instructions to processor 305 forexecution. The computer-readable medium is just one example of amachine-readable medium, which may carry instructions for implementingany of the methods and/or techniques described herein. Such a medium maytake many forms, including but not limited to, non-volatile media,volatile media, and transmission media. Non-volatile media includes, forexample, optical or magnetic disks, such as storage device 308. Volatilemedia includes dynamic memory, such as volatile storage 306.Transmission media includes coaxial cables, copper wire and fiberoptics, including the wires that comprise data bus 304. Transmissionmedia can also take the form of acoustic or light waves, such as thosegenerated during radio-wave and infra-red data communications.

Common forms of computer-readable media include, for example, a floppydisk, a flexible-disk, hard disk, magnetic tape, or any other magneticmedium, a CD-ROM, any other optical medium, punchcards, papertape, anyother physical medium with patterns of holes, a RAM, a PROM, an EPROM, aFLASH-EPROM, a flash drive, a memory card, any other memory chip orcartridge, a carrier wave as described hereinafter, or any other mediumfrom which a computer can read.

Various forms of computer readable media may be involved in carrying oneor more sequences of one or more instructions to processor 305 forexecution. For example, the instructions may initially be carried on amagnetic disk from a remote computer. Alternatively, a remote computercan load the instructions into its dynamic memory and send theinstructions over a telephone line using a modem. A modem local tocomputer system 300 can receive the data on the telephone line and usean infra-red transmitter to convert the data to an infra-red signal. Aninfra-red detector can receive the data carried in the infra-red signaland appropriate circuitry can place the data on the data bus 304. Thebus 304 carries the data to the volatile storage 306, from whichprocessor 305 retrieves and executes the instructions. The instructionsreceived by the volatile memory 306 may optionally be stored onpersistent storage device 308 either before or after execution byprocessor 305. The instructions may also be downloaded into the computerplatform 301 via Internet using a variety of network data communicationprotocols well known in the art.

The computer platform 301 also includes a communication interface, suchas network interface card 313 coupled to the data bus 304. Communicationinterface 313 provides a two-way data communication coupling to anetwork link 314 that is connected to a local network 315. For example,communication interface 313 may be an integrated services digitalnetwork (ISDN) card or a modem to provide a data communicationconnection to a corresponding type of telephone line. As anotherexample, communication interface 313 may be a local area networkinterface card (LAN NIC) to provide a data communication connection to acompatible LAN. Wireless links, such as well-known 802.11a, 802.11b,802.11g and Bluetooth may also used for network implementation. In anysuch implementation, communication interface 313 sends and receiveselectrical, electromagnetic or optical signals that carry digital datastreams representing various types of information.

Network link 313 typically provides data communication through one ormore networks to other network resources. For example, network link 314may provide a connection through local network 315 to a host computer316, or a network storage/server 317. Additionally or alternatively, thenetwork link 313 may connect through gateway/firewall 317 to thewide-area or global network 318, such as an Internet. Thus, the computerplatform 301 can access network resources located anywhere on theInternet 318, such as a remote network storage/server 319. On the otherhand, the computer platform 301 may also be accessed by clients locatedanywhere on the local area network 315 and/or the Internet 318. Thenetwork clients 320 and 321 may themselves be implemented based on thecomputer platform similar to the platform 301.

Local network 315 and the Internet 318 both use electrical,electromagnetic or optical signals that carry digital data streams. Thesignals through the various networks and the signals on network link 314and through communication interface 313, which carry the digital data toand from computer platform 301, are exemplary forms of carrier wavestransporting the information.

Computer platform 301 can send messages and receive data, includingprogram code, through the variety of network(s) including Internet 318and LAN 315, network link 314 and communication interface 313. In theInternet example, when the system 301 acts as a network server, it mighttransmit a requested code or data for an application program running onclient(s) 320 and/or 321 through Internet 318, gateway/firewall 317,local area network 315 and communication interface 313. Similarly, itmay receive code from other network resources.

The received code may be executed by processor 305 as it is received,and/or stored in persistent or volatile storage devices 308 and 306,respectively, or other non-volatile storage for later execution. In thismanner, computer system 301 may obtain application code in the form of acarrier wave.

It should be noted that the present invention is not limited to anyspecific types of wireless or wired network protocols. The requisitenetwork configuration may be achieved using a variety of knownnetworking protocols.
